Abstract
The effects of pollination by honeybees Aphis mellifera on yield and quality of eggplants were examined in forcing cultures at the lowest temperature of 15 °C. Yields of eggplants pollinated by honeybees and by bumblebees Bombus terrestris were equivalent, but the rate of unmarketable fruits pollinated by honeybees was higher than that by bumblebees. When germinative pollen count per one anther was 0.6 mg or more, the rate of unmarketable fruits pollinated by honeybees became equivalent to that by bumblebees. When eggplants were cultivated at the lowest temperature of 18 °C, the germinative pollen count per one anther rose to 0.6 mg or higher.
